DHS is using the U.S. Census to ask Americans, questions about smoke detectors, so they can to give homes ‘fire risk assessments’. The above video (approx. 2:30) shows how the New Orleans fire department “took it up a notch” and “went door to door, boots on the ground” entering resident’s homes to install smoke detectors in people’s bedrooms, kitchens etc.

I think it needs to be made clear that there is no suggestion that firefighters are being willing or knowing tools of DHS. Their motivation is generally to keep the community safe, and programs such as checking on smoke detectors to test them for residents or helping them install them are well-intended programs from the firefighters’ perspective.
